FASTENER FOR THE MEETING-RAILS OF SASHES- SPECIFICATION forming part of Letters Patent Nol 425,203, dated April 8, 1890.

Application filed January 6, 1890. Serial No. 336,050. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES HAZEN BROWN, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Fasteners for the Meeting-Rails of Sashes, of which the following is a specification.

This invention has for its object to provide a fastener for the meeting-rails of windowsashes which cannot be tampered with or unfastened by a person at the outside of the window without breaking the glass.

The invention consists in the provision of a vertical ear or lug on the meeting-rail of the upper sash, said car being either formed independently or cast with the holder of the fastening member on the upper sash, and provided with a slot formed to receive the pivoted lever which constitutes the fastening member on the upper sash when said lever is swung outwardly to engage the fastening member on the lower sash, the reception of the said lever by the said slot causing the ear or lug to firmly support the lever against upward pressure, such as might be caused by prying upwardly the lower sash.

The invention also consists in the provision of a pivoted latch on said ear or lug, said latch being adapted to engage the above-mentioned lever when it is in its sash-fastening position and prevent it from being swung back to unfasten the sashes by the insertion of a thin blade between the meeting-rails.

Of the accompanying drawings, forming a part, of this specification, Figure 1 represents a perspective View of portions of the meeting-rails of an upper and lower sash provided with my improvement. Fig. 2 represents a top plan view of the same. Fig. 3 represents a section on line 3 3 in Fig. 2. Fig. 4 represents a section on line i 4. of Fig. 2, looking toward the top of the sheet. Fig. 5

represents a similar view to Fig. a, showingthe fastening-lever in the position it occupies when the meeting-rails are not fastened. Fig.

6 represents a transverse section of the meet ing-rail of the upper sash, showing the improved construction of the holder for the fastening-lever without the ear or lug and the pivoted latch.

The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the meetingrail of the upper sash, and 1) represents the meeting-rail of the lower sash.

0 represents the sash-fastening lever, which is connected by a bolt or pivot d to a holder 6, attached to the rail a, and is adapted to engage a fastening member f of the usual or any suitable construction attached to the rail 1), the operation of the lever c and member f in fastening the sashes being the same as in the ordinary type of sash-fastener.

The holder eis preferably provided with a flange e, which is formed to bear against the vertical inner edge of the rail a, and is provided with one or more screw-holes to receive attaching-screws h, which pass horizontally through said flange into the rail a. The flange 6' may have a horizontal extension e, formed to bear on the under side of the rail a and attached thereto by screwspassing upwardly 'into the rail.

It represents alug or ear, whichis suitably attached to the rail a. Said lug or ear may be cast or otherwise formed with the holder 6, or it may be a separate piece attached to the rail or by independent screws. In the ear or lug 7; is formed a horizontal slot or recess Z, which is arranged to receive the lever c, as shown in Figs. 1, 2, 3, and 4, when said lever is in its sash-fastening position, the upper edge of the lever bearing against the upper edge of the slot Z, so that the ear or lug 76 supports the lever 0 against upward pressure and prevents said lever from being broken by extreme force used to raise the lower sash.

0 represents a latch, which is pivoted at p to the ear or lug 7c, and is formed with a shoulder 0', which is arranged to bear against one side of the lever 0 when the latter is in its sash-fastening position, and thereby prevent the lever from being displaced by the expedient often resorted to by-burglars of introducing a thin blade between the rails a b and pushing the lever c aside by said blade. The latch 0 has an inclined face 0', which is so arranged that when the lever c is being swung outwardly to fasten the rails a 1) its upper edge will strike said. inclined face and raise the latch 0 until the lever passes under the shoulder o, whereupon the latch drops to the position shown in Figs. 1, 3, and in \Yhen the latch is engaged with the lever c, the latter cannot be moved to nnfasten the rails a I) until the latch is raised, and as the latch located at one side of the crevice between the meeting-rails it is evident that said latch cannot be moved by any person at the outside of the window unless the glass is broken.

I claim as my invention- 1. In a saslrfastencr, the combination, with the lever 0, its holder (2, and a fastening memberf, arranged to cooperate therewith, of a vertical ear or lug ls, bearing against and attached to the vertical inner face of the meeting-rail of the upper sash, said lugs projecting above said rail and having a slot or recess Z, arranged to receive said lever when it is in its fastening position, whereby the lever is supported against upward pressure, as set forth.

2. The combination, with the lever 0, its holder 0, and the fastening member], of the ear or lug 7:, adapted for attachment to the upper sash, and provided with the slot Z, {LY-- ranged to receive the lever c, and the latch 0, pivoted to the ear 7.t, and adapted to engage the lever c and hold the same in the slot 1, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 2d day of Jannary, A. D. 1890.
